3300 6.0 CO Trunks Not Disconnecting

[x-man]

try increasing the disconnect time up to an beyond 800 msec if needed. Some lines here in blighty are set to 800 msec diconnect clear time and need a time close to that for the disconnect to work.

Or get your line provider to tell you what they set the disconnect clear time to...just keep phoning them and pestering them till you get an answer. Thats what I do with BT here.

You might have to put an analog meter on the line to see if there's a disconnect at all.

I have tried the pestering thing.  They actually found it funny, like dangling the carrot.
I did the analog meter thing.  See below:

line voltage: 48 volts
far-end caller rings: needle fluctuates
call pickup & connect: voltage drops real low (cant remember the reading)
far-end hangs up: voltage drops to about 0 then rises slightly above the "call connect" reading

voltage stays there for over 40 seconds until I manually dicsonnect quickly rises to 48 volts

Is this what is expected?
